How do I transfer my progress to a new device?

To sync your progress across Apple devices with the same Apple ID, do the following:

1. Tap the gear icon in the top right corner.
2. Tap Settings.
3. Turn on Back Up Progress on both devices.
4. On each device, go to the iPhone's settings, tap your name, then iCloud, and select Show All.
5. Enable iCloud sync for the Nonogram app on both devices.
